WILSONVILLE, Ore.—(BUSINESS WIRE)—May 8, 2007—
Mentor Graphics Corporation, (NASDAQ:
MENT), today announced that
its suite of advanced synthesis products supports the newly introduced
Arria GX field programmable gate arrays (FPGAs) from Altera
Corporation. Both companies have been in close cooperation to ensure
Precision(R) Synthesis support for the full range of Arria GX devices
with release 2007a3.

Arria GX, Altera's latest family of FPGA devices, is designed to
deliver protocol-optimized transceivers at a cost point attractive to
high-volume applications. "Arria GX expands Altera's already
impressive offering of FPGAs, broadening the portfolio of products
with integrated transceivers," said Simon Bloch, general manager,
Mentor Graphics Design Creation and Synthesis Division. "Designers
using Arria GX FPGAs will benefit from the advance features of
Precision Synthesis to meet their design goals both predictably and
rapidly."

The companies began collaboration late last year on supporting the
Arria GX FPGA family within the Mentor Graphics family of synthesis
tools. "Precision Synthesis' high quality of results, advanced design
optimization and analysis capabilities enable users to reduce costs
and accelerate the overall design process," said Danny Biran, vice
president of product and corporate marketing at Altera. "We recommend
Precision Synthesis to our customers for all Altera families including
our new Arria GX family."

As a part of the Mentor Graphics synthesis product line,
LeonardoSpectrum(TM) offers customers a well-proven, mature synthesis
solution for both FPGAs and ASICs.
